The cubes are made of a gold-platinum alloy to minimize the magnetism that could act on them.
And both the laser and the fruit fly are moving as that operation unfolds.
The frequency of orbiting objects is determined by how often they complete a full orbit around each other.

You literally cant do it.
You have to go to space, one way or another.
In 2023, a group of pulsar timing array collaborations found strong evidence of agravitational wave backgroundin pulsar data.

If black holes were porridge, LISA would be Goldilocks.
and are we alone?'
But the how did we get here is pretty important to understand these black holes.

LISA will observe the churning of black holes and better characterize the array of compact objects in our universe.
That information can also be applied to existing cosmological models and prevailing theories, such as Einsteins general relativity.
This article was updated to clarify ESAs leading role in the LISA mission.
